If the temperature of the atmosphere is increased,which of the following characteristics of a sound wave is affected?

Which of the following frequencies of sound waves is audible to human beings?

What will be the shape of the graph of the speed of sound in air versus pressure at a constant temperature?

Sound waves are not transmitted over long distances because:

Two monoatomic ideal gases '$1$' and '$2$' of molecular masses $m_1$ and $m_2$ respectively are enclosed in separate containers kept at the same temperature. The ratio of the speed of sound in gas '$1$' to that in gas '$2$' is

$A$ steel rod $100\, cm$ long is clamped at its middle. The fundamental frequency of longitudinal vibrations of the rod is given to be $2.53\, kHz$. What is the speed of sound in steel? (in $km/s$)
